mk1 laguna

Hi just got a 1999 mk1 facelift laguna, as expected it has a couple of problems, central locking does not work on remote ( I have changed the batteries) rear window heater not working and the drivers seat is broken looks like the bolt to the frame has been pulled though. I need to sort out the drivers seat first and was wondering if anyone knows if a mk11 seat would fit? or do I have to find a mk1 seat
